In recent decades, global warming has intensified hydrological cycles, raising concerns about the impacts of climate change on hydrological processes, water quality, and water resources across various temporal and spatial scales. These changes significantly affect water resource management and environmental protection policies and may also influence the ecological health and socio-economic well-being of lake regions. Qinghai Lake, the largest inland lake and a major water source reservoir in China, plays a crucial role in the ecological security of the Qinghai-Tibet Plateau. However, in recent years, with the ongoing development of the economy and society throughout the province, there has been an increase in algal blooms in the nearshore area of Qinghai Lake, with the affected area expanding annually. There is currently no clear consensus on the causes of eutrophication in lakes, and comprehensive, in-depth research on how different land use types-critical to the material migration and transformation processes of natural water bodies-affects water quality and ecological security, as well as the interactions between nutrients and heavy metals, is lacking. Therefore, it is essential to monitor and understand the effects of climate change on lakes and to develop adaptive strategies to mitigate and respond to these impacts amidst rapid economic and social development. The lake environmental pollution early warning system developed in this study provides a scientific research paradigm for lake water pollution control and offers valuable data support for policymakers in formulating ecological protection and development strategies.
近几十年来，全球变暖加剧了水文循环，引发了人们对气候变化在不同时空尺度上对水文过程、水质和水资源影响的担忧。这些变化对水资源管理和环境保护政策产生了重大影响，也可能影响湖泊地区的生态健康和社会经济福祉。青海湖是中国最大的内陆湖和主要水源地，对青藏高原的生态安全起着至关重要的作用。然而，近年来，随着全省经济社会的不断发展，青海湖近岸区域藻类水华现象增多，受影响面积逐年扩大。目前对于湖泊富营养化的成因尚无明确共识，缺乏对不同土地利用类型（对天然水体的物质迁移和转化过程至关重要）如何影响水质和生态安全以及营养物质与重金属之间相互作用的全面、深入研究。因此，在经济社会快速发展的背景下，监测和了解气候变化对湖泊的影响，并制定适应性策略来减轻和应对这些影响至关重要。本研究开发的湖泊环境污染预警系统为湖泊水污染控制提供了一种科研范式，为政策制定者制定生态保护和发展战略提供了有价值的数据支持。
